TECHNICAL FIELD

The present disclosure relates generally to voicemail platforms for communications devices. More particularly, the present disclosure relates to systems and methods for consolidating wireline and wireless voicemail boxes.

BACKGROUND

Voicemail is a popular telephone service feature, and is often included in the price paid for telephone service. When a called line with voicemail functionality does not answer or is busy, a call can be handled by a voicemail system. A voicemail system can store recordings and/or announcements for a user. When a call is passed to a voicemail system, the voicemail system can play one or more recordings and/or announcements for the calling party or a generic message and can prompt the calling party to leave a message, for example, a spoken message. The voicemail system can record the calling party's message and store the message, for example, as audio data in a storage device. Call data associated with the message, for example, the calling party's telephone number, the date and time of the call, and the like, can also be stored by the voicemail system and associated with the stored message. Some voicemail systems also allow calling parties to leave alphanumeric messages for a called party. In any event, the voicemail system can store the message or data and associated call data.

Among the close to 100 million cellular telephone service users in the United States, a growing trend includes making a cellular telephone service a user's primary telephone service. As such, a user's cellular telephone service, and voicemail service associated with a cellular telephone line, can be relied upon by a user to report most, if not all, missed telephone calls, whether those calls relate to personal or business matters.

The increased reliance upon cellular telephone service has been accompanied by a corresponding increased demand and increased reliance upon other cellular telephone features and functionality, for example, text messaging, email, Internet browsing, voicemail, data transfer, and other features. As reliance upon and demand for cellular telephone services and voicemail increases, demand for enhanced voicemail services will likely continue to experience a corresponding increase.

SUMMARY

A system for storing at least one voicemail message at a master voicemail system can include at least one slave voicemail system in communication with a master voicemail system. The voicemail message can be associated with a call received by the slave voicemail systems or the master voicemail system. A call can be handled by the voicemail system that receives the call, or the call can be transferred to another voicemail system for handling. Handling can include storing a message in one or more formats, storing call data associated with the call, generating source data associated with the message, associating various message components with one another to represent a message, and storing the message in a memory location. One or more of the voicemail systems can be connected to a cellular network. A device can be in communication with the cellular network and to the master voicemail system. The at least one voicemail message can be transferred from the MVMS to the device and stored by the device in a device memory. The at least one voicemail message can include audio data, text data, video data, or a combination thereof. The voicemail system can include additional functionality including, but not limited to, translation applications, forwarding applications, conversion applications, speech to text applications, combinations thereof, and the like.

A method for consolidating voicemail messages associated with multiple voicemail systems can include receiving a call at a voicemail system, and storing a message associated with the call at a voicemail system memory. The method can further include determining at the voicemail system if the voicemail system is configured as a slave voicemail system or a master voicemail system. In some embodiments, if the voicemail system is configured as a slave voicemail system, the method can include passing the call to a master voicemail system. The storing can include storing the message and call data at a memory location associated with the master voicemail system. In other embodiments, if the voicemail system is configured as a slave voicemail system, the method can include storing message content and call data at a memory location associated with the slave voicemail system and transferring the stored message content and call data to the master voicemail system. In some embodiments, the master voicemail system generates data relating to the voicemail system to which the call was originally directed, and associates the generated source data with the message content and the call data. In other embodiments, if the voicemail system is configured as a slave voicemail system, the method further includes storing message content and call data at a memory location associated with the slave voicemail system, sending a notification to the master voicemail system that a message has been deposited at the slave voicemail system, receiving, at the slave voicemail system a request to transfer the stored message content and call data to the master voicemail system, and transferring the stored message content and call data to the master voicemail system. The storing a message can include storing audio data, text data, video data, or combinations thereof.

A device for storing messages associated with at least two voicemail systems can include a memory for storing messages and a communications component for communicatively coupling the device with a master voicemail system. The communications component can include one or more transceivers. The master voicemail system can be configured to store messages associated with the at least two voicemail systems, and to transfer the messages to the device. The messages can be stored as audio data, text data, video data, or a combination thereof. One or more of the voicemail systems can be plain old voicemail systems and/or visual voicemail systems.

These and additional features of the present disclosure will become apparent with reference to the attached drawings, wherein:

FIGS. 3 and 4 schematically illustrate an exemplary method 100 for voicemail message deposit and subsequent retrieval of message content for local storage on a mobile device, according to some exemplary embodiments of the present disclosure. It should be understood that the steps described are not necessarily presented in any particular order and that performance of some or all of the steps in an alternative order(s) is possible and is contemplated. The steps have been presented in the demonstrated order for ease of description and illustration. Steps can be added, omitted and/or performed simultaneously without departing from the scope of the appended claims. The method 100 can be terminated at any time. Some or all steps of this process, and/or substantially equivalent steps, can be performed by execution of computer-readable instructions included on a computer readable medium.

In an attempt to simplify the description of the method 100, some steps, network elements, and nodes have been omitted from FIGS. 3 and 4. Similarly, messages and data are described and illustrated in generic terms, though it will be appreciated that multiple message and data formats, as well as multiple message and data nodes, relays, and messaging platforms can be involved in any or all of the communications described herein.

In an additional attempt to simplify the description and to avoid complicating the disclosure, the following description will describe, in general terms, performance of various systems and methods embodying some concepts of various embodiments of the disclosure. In reading the description of the several embodiments disclosed herein, it should be understood that a user can interact with a voicemail system, for example, the voicemail systems 24, 26, and 28, using a telephone user interface (TUI), a GUI, a web UI, or another UI. Alternatively, a user can interact with the device 18, and the device 18 can handle all communication needed to instruct the MVMS 28 how to carry out the user's desired actions. Therefore, DMTF-driven TUIs, icon-based GUIs, touch-sensitive screen GUIs, web UIs, voice-driven TUIs, and the like are included in the following descriptions of the exemplary method 100 disclosed herein and are included in the scope of the appended claims.

As illustrated in FIG. 3, the exemplary method 100 can begin and can proceed to block 110, wherein a call is received at a voicemail system, for example, an SVMS 24, 26, or an MVMS 28. As will be explained in more detail below, a call can be received directly at the voicemail system, or can be forwarded to the voicemail system from another voicemail system. It should be appreciated that the word “forward,” as used in this description and in the claims includes multiple contemplated methods of transferring and/or consolidating calls and/or voicemail messages at an MVMS 28. For example, one embodiment includes forwarding incoming calls from an SVMS 24, 26 to an MVMS 28, and storage of message content and call data by the MVMS 28. In another embodiment, the SVMS 24, 26 obtains and stores voicemail messages and transfers to the MVMS 28 message content and call data. In another embodiment, the SVMS 24, 26 obtains and stores message content and call data and forwards to the MVMS 28 a notification that indicates to the MVMS 28 that messages are waiting. The MVMS 28 can connect to the SVMS 24, 26 and download message content and call data. These and other embodiments are included within the scope of the appended claims.

As shown at block 112, the method 100 can proceed in at least two different ways. If the voicemail system is an MVMS 28, the method 100 can proceed to block 114, which will be described in more detail below. If the voicemail system is an SVMS 24, 26, the method 100 can proceed to block 116, wherein the SVMS 24, 26 can check the settings to determine how to handle the incoming call. If the SVMS 24, 26 is configured to forward incoming calls to an MVMS 28, the method 100 can proceed to block 118, whereat the SVMS 24, 26 can forward the incoming call to the MVMS 28. If the SVMS 24, 26 is configured to handle the call, then the method 100 can proceed to block 120, whereat the SVMS 24, 26 can obtain a message and call data associated with the incoming call. Although not illustrated, obtaining a message can include playing a greeting, prompting a calling party for a message, recording an audio, video, or text message, converting the message to a desired format, translating a message or a portion thereof, converting speech to text, and/or other functions. As illustrated at block 122, the SVMS 24, 26 can store the message(s) and associated call data in a memory (not illustrated).

The method 100 can proceed to decision block 124, whereat the SVMS 24, 26 can check the settings to determine how to consolidate messages at the MVMS 28. If the SVMS 24, 26 is configured to send a notification to the MVMS 28, then the method 100 can proceed to block 126, whereat the SVMS 24, 26 can send a message waiting notification to the MVMS 28. It will be appreciated that the SVMS 24, 26 can direct other network nodes to send one or more notifications to the MVMS 28 in one or more formats. Exemplary formats include short message peer-to-peer (SMPP), domain name server (DNS) protocol, lightweight directory access protocol (LDAP), unstructured supplementary service data (USSD) protocol, Internet message access protocol version 4 (IMAP4), and hypertext transfer protocol (HTTP), HTTP over secure sockets layer (HTTPS), other message formats, and the like. These formats and nodes will not be discussed here in detail for the sake of brevity.

The SVMS 24, 26 can receive, from the MVMS 28, a request for message content and/or call data, as shown at block 130. At block 128, the SVMS 24, 26 can transfer, or direct other network nodes to transfer, the message content and/or call data to the MVMS 28. The message content and call data can be transferred to the MVMS 28 using a data session, a voice session, or both. The method 100 can then proceed to block 134 as shown by the on-page reference B. It should be understood that in addition to, or instead of, sending a request to the SVMS 24, 26 for message content and/or call data, the MVMS 28 can connect to the SVMS 24, 26 to retrieve message content and/or call data. Returning briefly now to decision block 124, if the SVMS 24, 26 is configured to transfer message content and call data to the MVMS 28, the method 100 can proceed to block 128. The message content and/or call data can be transferred to the MVMS 28 using a data session, a voice session, or both. The method 100 can then proceed to block 134 as shown by the on-page reference B.

As discussed above, the method 100 can proceed to block 114 from block 112, or from block 118. At block 114, the MVMS 28 receives an incoming call. As illustrated at block 132, the MVMS 28 can obtain a message and call data from the incoming call. As explained briefly above, obtaining a message can include playing a greeting, prompting a calling party for a message, recording an audio, video, or text message, converting a message, translating a message, and/or other functions. The method 100 can proceed to block 134 from block 132 or from block 128. At block 134, the MVMS 28 can create a source tag for the message content and call data. For purposes of the description and the appended claims, the term “source tag” includes data that indicates the source of message content and call data. The source tag can be appended to a message, made a part of the message, associated with a message, inserted into the message headers, combinations thereof, and the like. The source tag can be used to indicate the source of a message. For example, if the incoming call was originally received at an SVMS 24 associated with a user's work telephone line, the source tag can indicate that the message content and call data is associated with the work telephone line. The source tag can be interpreted by the MVMS 28, the device 18, or other network element or device connected thereto, to denote that the message is from a work voicemail system. The use of source tags can allow multiple voicemail systems to consolidate messages at a centralized voicemail system, while allowing a user or device to associate messages with a consolidated voicemail system. As illustrated at block 136, the MVMS 28 can associate a source tag with a message and store the message, the call data, and the source tag in a memory as a message. The method 100 can proceed to FIG. 4.

FIG. 4 schematically illustrates additional methodology of the exemplary method 100 for voicemail message deposit and subsequent retrieval of message content for local storage on a mobile device. As explained above with reference to FIG. 3, it should be understood that the steps illustrated and described in FIG. 4 are not necessarily presented in any particular order and that performance of some or all of the steps in an alternative order(s) is possible and is contemplated. The steps have been presented in the demonstrated order for ease of description and illustration. Steps can be added, omitted and/or performed simultaneously without departing from the scope of the appended claims. Some or all steps of this process, and/or substantially equivalent steps, can be performed by execution of computer-readable instructions included on a computer readable medium.

The illustrated method 100 begins with a message being deposited at the MVMS 28 as illustrated and described above with reference to FIG. 3. Messages can be deposited at the MVMS 28 directly, or indirectly, as explained above with reference to FIG. 2. In the illustrated embodiment, the MVMS 28 notifies the CDS 30, for example, by generating a SMPP notification message (notification_SM) that is sent to the CDS 30, as shown at step 140. A notification_SM message can include, but is not limited to, the hostname and port number for the subscriber's CDS 30, a token identifying the subscriber's MVMS 28, the subscriber's voicemail box ID embedded with a token to uniquely identify the subscriber for the MVMS 28, and the current VMS password. In some alternative embodiments, the notification_SM includes an IP address and port number for the subscriber's CDS 30 and a mailbox_ID. The password and token can be added to help increase security and to help preserve data integrity. If a password is used, the password can be encrypted or unencrypted, and/or the password can be obscured to hide the actual default password digits.

The CDS 30 can forward the notification_SM message, at step 142, to the SMSC 32 that, in turn, can forward the message, at step 144, to the device 18. The device 18 receives the notification_SM message and generates an HTTP get_headers command/message that is sent to the CDS 30, at step 146. The get_headers message can include parameters such as the date, time, and calling line identity (CLI). The get_headers message can additionally include authentication information for IMAP sessions between the CDS 30 and MVMS 28. At step 148, the CDS 30 initiates an IMAP session with the MVMS 28. Accordingly, a TCP connection is established and the get_headers message is used to authenticate the session, after which the subscriber's voicemail box is accessed on the MVMS 28 to retrieve the header information for the voicemail messages. The MVMS 28 sends the headers to the CDS 30, at step 150. The CDS 30 forwards the headers to the device 18, at step 152. The device 18 uses the headers to determine the status of each message stored on the device 18 and identify any deposited messages or changes to messages. After the device 18 determines which message(s) needs to be retrieved, the device 18 generates and sends a message request, for example, an HTTP get_message request with the header information for the requested message(s), at step 154. At step 156, this message is received and the CDS 30 generates and sends an IMAP message_request, including the requested voicemail message header information, to the MVMS 28. The MVMS 28 processes the request and returns the requested message content in an IMAP message_response, at step 158. The CDS 30 then delivers the designated message content to the device 18, at step 160. Upon receipt of the message content, the device 18 stores the content under the appropriate header in a memory and permits the subscriber to access the content via a user interface, for example, a GUI. The message content can be formatted using any audio CODEC, such as, but not limited to, adaptive multi-rate (AMR), AMR wideband (AMR-WB), or any other standardized or independent audio CODEC, including, but not limited to waveform audio (WAV), audio interchange file format (AIFF), RAW, encoded in GSM CODEC, advanced audio coding (AAC), MPEG-1 audio layer 3 (MP3), MPEG-4 Part 14 (MP4 or M4A), Windows® media audio (WMA), RealAudio (RA), free lossless audio codec (FLAC), Apple® lossless encoder (ALE), i.e., Apple® lossless audio codec (ALAC), and other open and proprietary audio formats.

In certain embodiments, an “if-modified-since” HTTP Message can be used to occasionally poll the MVMS 28 for the Inbox voicemail message list and update any voicemail message “if-modified-since” the last update, for example, if a message was deleted or added at the device 18 or the MVMS 28. This can help reduce the amount of data traversing the network, thereby reducing network congestion. However, in some embodiments the header information is relatively small and as such no noticeable improvement may be available for sending only the modified voicemail message header.

In certain embodiments, more than one connection can be established to the MVMS 28 or in some cases to multiple or redundant VMSs. This can allow simultaneous requests in order to serve a subscriber's request to view or listen to a message faster. In some other embodiments, messages are transferred to a device 18 upon receipt by the MVMS 28. Load balancing techniques can also be implemented. In certain embodiments, message downloads that are interrupted, for example, via cancellation or connection failure, can be resumed starting at the last received byte. These embodiments assume the message is stored in full, at least temporarily, on the CDS 30. However, in some embodiments, the CDS 30 deletes the message after the message content is sent to the device 18. A subsequent request for one or more previously sent messages is facilitated by re-retrieving the message, re-transcoding the message, and sending the message to the device 18. In certain embodiments, requests to the CDS 30 can be pipelined in accordance with HTTP 1.1 specifications. This can help reduce network latency for multiple requests.

FIG. 5 illustrates an exemplary representative image from a GUI 200 for a device 18, according to an exemplary embodiment of the disclosure. As has been explained above, the voicemail systems 24, 26, 28 can be configured and/or controlled with a variety of UIs, including, but not limited to, a GUI 200 on a device 18. As such, the GUI 200 illustrated in FIGS. 5-8 is a general illustration of one embodiment of a UI, illustrated solely for the purpose of explaining how a user can tailor and/or control the one or more voicemail systems. The illustrated GUI 200 should not be understood as a limiting embodiment. It must therefore be understood that various menu options, settings, passwords, and the like, can be controlled and/or tailored by interfacing with one or more VMSs through a TUI, a GUI, a Web UI, a network operator, and the like. In the illustrated embodiment, an exemplary visual voicemail client UI is used to control the voicemail consolidation menus and functions.

As illustrated, the GUI 200 can include operational information 202 for the device 18. The operational information 202 can include network information, for example, a signal meter 204 for displaying the measured strength of a network signal, and a network indicator 206 for displaying the current network to which the device 18 is connected. In the illustrated GUI 200, the device 18 is indicating a maximum signal strength and that the device 18 is currently connected to the AT&T EDGE (Enhanced Data rates for GSM Evolution) network. It should be understood that this indication is exemplary only since the GUI 200 can be used on devices operating on other networks and operated by other carriers. The operational information 202 can also include, for example, the time of day 208, a battery meter 210, as well as other indicators, including, but not limited to, a short range radio communications device indicator, an alarm indicator, a date, and the like.

In the illustrated GUI 200, an exemplary visual voicemail application user interface (VVMAUI) 212 is currently displayed. The illustrated VVMAUI 212 includes a title and/or menu portion 214, a mailbox contents portion 216, and a control portion 218. The mailbox contents portion 216 can display one or more messages 220, 222, 224, 226. The control portion 218 can include one or more controls, if desired. The illustrated control portion 218 includes a callback option 228, a delete option 230, and a time slider bar 232. Additional options, menus, functions, and the like can be displayed, but are not illustrated in FIG. 5.

In some embodiments, the GUI 200 is controlled by using buttons, soft-buttons, joysticks, switches, wheels, or the like on a device keypad. In other embodiments, the voicemail client is run using an input/output device operatively connected to the device 18. In other embodiments, the GUI 200 also functions as a touch-sensitive input device for accepting user input, whereby a user can touch the screen at a desired option to enter a command corresponding to the selected option. In still other embodiments, a combination of input devices are used to make desired selections. These and other embodiments are included in the scope of the appended claims.

As illustrated, some or all of the messages 220, 222, 224, 226 can include an indication 234, 236, 238 as to the voicemail system at which the message was left, or was intended to be left. The indicators 234, 236, 238 can be generated by a network element, a VMS 24, 26, 28, or the device 18, and can be based at least partially upon source tags or header data included with, associated with, and/or embedded in the message data. In the illustrated exemplary embodiment, the indicators 234, 236, 238 are icons. The messages 220 and 224 include “W” icons 234 and 236, indicating that the calls from which messages 220 and 224 were saved were directed to the user's work telephone line. The message 226 includes an “H” icon 238, indicating that the call from which the message 226 was saved was directed to the user's home telephone line. The message 222 includes no icon. In the illustrated embodiment, the absence of an icon next to the message 222 indicates that the message 222 was directed to the telephone line associated with the MVMS 28. It will be appreciated that an icon or other indicator could be included for any, all, or no messages.

It should be understood that the indicators 234, 236, 238 are exemplary only and that other types of indicators are contemplated and included in the scope of the specification and the appended claims. For example, in some embodiments, the inbox includes folders for some or all of the associated voicemail system. Messages associated with the voicemail systems can be stored in respective folders, thereby indicating the source of the messages in the respective folders. In other embodiments, each message is color coded according to the source voicemail system. For example, home voicemails could be a first color, work voicemails could be a second color, and mobile voicemails could be a third color. Similarly, source can be indicated by, for example, font, color, picture, text, video, animations, audio, font size, combinations thereof, and the like. Other visual or audio indicators are contemplated, but will not be set forth in detail for the sake of brevity.

It should also be understood that the exemplary GUI 200 could include other information relating to the messages, message content, call data, the associated voicemail system, and the like. For example, the GUI 200 could display message size, message type, message length, priority codes, and the like. Some additional indicators are discussed below with reference to FIG. 8.

FIG. 6 illustrates another exemplary representative image from a GUI 200 for a device 18, according to an exemplary embodiment of the disclosure. In FIG. 6, the user has entered a settings menu for a visual voicemail client. It should be stressed that the illustrated GUI 200, the options represented therein, the text of the options, and the controls presented, are exemplary only, and represent only one contemplated exemplary embodiment. The illustrated menu includes a submenu 240 for setting message format delivery options. In the illustrated submenu 240, the user has the option to toggle on or off delivery of audio voicemails and text voicemails. Text voicemails can be left by calling parties, or generated by a speech to text application from audio or video messages. Additionally or alternatively, text voicemails can be generated by translation software from text, video, or audio messages. As such, the illustrated menu can include options relating to translation, for example, enabling translation, setting default languages, and the like. As illustrated in FIG. 6, any, none, or all of the delivery formats can be turned on or off.

The illustrated menu also includes a submenu 242 for managing accounts and account settings associated with the voicemail systems. In the illustrated menu, a home, mobile, and work account are shown, as is an option to add an additional account. Any number of accounts can be consolidated using embodiments of the present disclosure, and hence any number of accounts can be listed in the edit accounts list or submenu 242. The illustrated submenu 242 also includes an option to add an account.

FIG. 7 illustrates another exemplary representative image from a GUI 200 for a device 18, according to an exemplary embodiment of the disclosure. The GUI 200 is displaying an exemplary menu for editing the home voicemail account, for example, if the user selects the home account under the edit account settings submenu 242.

The illustrated GUI 200 includes an option 244 to set a nickname for the selected account, allowing a user to associate a recognizable word or phrase with an account. In the illustrated example, the user has entered the word “Home” as the nickname. The illustrated GUI 200 also includes an option 246 for entering a dial in number for the associated voicemail box. This option 246 may be necessary depending upon how the MVMS 28 retrieves message content transfers from an SVMS 24, 26. The dial-in number can be used by the MVMS 28, for example, for authentication purposes, or for purposes of connecting to an SVMS 24, 26 for downloading messages.

The illustrated GUI 200 also includes an option 248 for entering a password (PW) or personal identification number (PIN). As shown in FIG. 7, the PW or PIN can be obscured by the device 18 to prevent inadvertent disclosure of the PW or PIN to unauthorized parties. The illustrated GUI 200 can also include an option 250 for toggling on or off the forwarding of voicemails and/or telephone calls associated with the account. A user may wish to deactivate the account forwarding option, for example, when the user travels abroad. While abroad, the user may wish to limit roaming data for purposes of avoiding high costs associated with roaming data. By deactivating the account forwarding option, the user can prevent new messages from the account from being forwarded to the device 18, thereby reducing data traffic to/from the device 18.

The illustrated GUI 200 also includes an exemplary menu 252 for setting the account type of the selected account. In the illustrated GUI 200, the user has designated the “Home” voicemail system as a slave account, the significance of which is described above with reference to FIG. 3. The menu 252 also includes an option to adjust additional settings of the voicemail account, for example, the frequency of queries for new messages, the voicemail system to which a voicemail system forwards messages, message time limits, message formats, conversion settings, text, audio, and video settings, translation settings, and the like. Although these and other additional settings are not illustrated in FIG. 7, it should be appreciated that a user can determine how and if the voicemail system interfaces with other voicemail systems designated by the user, including setting some or all of the options described above with reference to FIGS. 3-6.

With particular reference to FIG. 3, and by way of example, and not limitation, the user can set whether the SVMSs 24, 26 handle incoming calls, transfer the calls to an MVMS 28 for handling, and whether the SVMSs 24, 26 store and forward messages to an MVMS 28, or store messages and send notifications to the MVMS 28 of messages waiting. If the voicemail system is an MVMS 28, the user can set which voicemail systems deposit messages to the MVMS 28, and the like. The user can also enter authentication information for some or all voicemail systems, if desired. If the SVMSs 24, 26 store messages, the user can set whether the MVMS 28 connects to the SVMS 24, 26 using a data connection, voice connection, and the like. Additional settings can be included, though not illustrated. It should be understood that some or all of the settings can be set at voicemail systems using a TUI, a web UI, a device GUI, and the like. It should also be understood that some or all voicemail system settings can be set by the network operator or another authorized party. The user may, or may not, be able to customize these and other settings.

The illustrated GUI 200 also includes two exemplary menu options 254, 256. The illustrated menu options are exemplary only. Additional or alternative menu options are possible and contemplated, for example, an option to edit, select, and/or designate an icon selection for a voicemail system. The illustrated back option 254 can be used to navigate to a previous, additional, or parent menu or directory. The delete option 256 can be used to delete the selected account, for example. In the event that the delete option 256 is selected by a user, the account as set up at the device 18 can be deleted. However, it will be appreciated that the account may not be deleted from the telephone system with which the voicemail account is associated.

While the description of FIG. 7 has set forth some of the exemplary options available for customization, the systems and methods for updating voicemail system settings at/with respective telephone networks has not been described in detail. It should be appreciated that selection of certain options at the device 18 may not effect any changes at an associated voicemail system without communication between the device 18 and one or more associated voicemail systems. For example, if a user elects to make a voicemail system a slave voicemail account, the device 18 will need to communicate this selection with one or more voicemail systems. It should be appreciated that a user may need to set these options via a web UI, a TUI, through a network operator, or the like, according to preferences, capabilities, and needs of a network or network operator, for example. It should be appreciated that multiple messaging platforms, protocols, and systems can be used to effect the messaging between and among users, devices 18, voicemail systems 24, 26, 28, and/or communications networks 10. Exemplary formats include, but are not limited to, short message peer-to-peer (SMPP), domain name server (DNS) protocol, lightweight directory access protocol (LDAP), unstructured supplementary service data (USSD) protocol, Internet message access protocol version 4 (IMAP4), and hypertext transfer protocol (HTTP), HTTP over secure sockets layer (HTTPS), other message formats, and the like, many of which have been discussed above with respect to communication between the device 18 and the voicemail systems 24, 26, 28.

FIG. 8 illustrates another exemplary representative image from a GUI 200 for a device 18, according to an exemplary embodiment of the disclosure. In the illustrated GUI 200, the messages 220, 222, 224, 226 and indicators 234, 236, 238 described in FIG. 5 are illustrated. Additionally, the exemplary GUI 200 illustrated in FIG. 8 includes message-type indicators 258, 260. In the illustrated embodiment, the message-type indicators 258, 260 are icons, though alternative indicators are contemplated, as explained with respect to the icons 234, 236, 238 of FIG. 5.

The message-type indicator 258 is an icon that informs a user that the message includes a text portion. The message-type indicator 260 is an icon that informs a user that the message includes an audio portion. Messages with both message-type indicators 258, 260 inform a user that the message includes a text portion and an audio portion. It should be understood that additional message formats, for example, video messages, SMS messages, text files, and the like, can be included in the inbox and can be denoted by additional message-type indicators. With reference to the first message 220, the GUI 200 displays information that informs the user of the name of the party who left the message, in this case, Lars Ulrich, the voicemail system to which the call was originally directed, in this case, the user's work telephone line, the date of the message, in this case, Apr. 18, 2008, the duration of the message, in this case, 0 minutes and 37 seconds, and the message-type, in this case a text voicemail and an audio voicemail. Other information, for example, priority levels, calling party presence indicators, and the like, can be displayed as well. A user can use some or all of the displayed information to screen messages or to prioritize messages without listening to or viewing the message content.

While the preceding description has described voicemail messages primarily in the context of audio and text messages, it should be appreciated that the VMSs 24, 26, 28 can also process, store, transfer, download, forward, and consolidate (handle) video messages, if desired. In the event that the VMSs 24, 26, 28 are configured to handle video messages, many of the same processes described above with respect to video and text messages can be used to handle the messages. For example, a video file can include a video component and an audio component. As such, the VMS 24 can record, store, forward, transfer, download, and/or consolidate the audio file, the video file, or both. The conversion can include a speech to text converter, CODECs, and the like, as explained above. As such, a VMS 24, 26, 28 can receive, store, transfer, download, forward and/or consolidate messages as video, audio, text, combinations thereof, and the like.

It must be understood that the illustrated GUIs are exemplary only and other contemplated user interfaces, screen layouts, selection methods, and the like are contemplated, including an embodiment of the VMS 24, 26, 28 that does not provide a GUI at the user's device, the calling party's device, or either device. Furthermore, a selection can be made using various embodiments of softkeys and/or key selections on a mobile or stationary telephone keypad, for example, and is not limited to the illustrated GUI. Additional and/or alternative selector switches and joysticks can be used to select a desired option or icon corresponding to a desired option. Input methods can also include touch screens or voice commands. Any desired screen layout or format can be used, including plain text and icons, for example.

It should also be understood that different delivery methods and/or systems may be required to deliver text voicemail messages and other voicemail messages, e.g., audio, video and/or visual voicemail messages. In some embodiments of the present disclosure, the audio, video, and/or text portions can be combined and stored as one item, as illustrated in FIG. 8. It should be appreciated that providing this feature may require associating the different formats with one another, for example, by assigning identifying data to the message components and associated the message components to reflect that the message components are related. This can allow the two or more message types to be joined into one menu item. If the message components are delivered independently of one another, the first delivered message component can create the message entry at the device. If a message format is not available, or is disabled, then the visual voicemail UI can include a place holder indicating that the missing portion of the message is not available. For example, if a translation or speech to text module is disabled, an indication that a text or audio portion of a message can be included to inform the user accordingly. Alternatively, the place holder can be blank if no text portion is available, as was illustrated in FIG. 8. If a user's account does not support delivery of a format, then the UI could be configured to omit any indication of that format, for example. Other iterations, options, and combinations are contemplated and included in the scope of the appended claims.

It should also be understood that the methods and systems illustrated in FIGS. 1-8 are exemplary and that other embodiments are contemplated. For example, in some embodiments, the MVMS 28 can be programmed with more than one greetings, and one or more of the greetings can correspond to one or more SVMSs 24, 26. As such, the MVMS 28 can be configured to play a greeting corresponding to the voicemail system 24, 26, 28 to which the incoming call was originally directed. Such functionality can help reduce confusion on the part of a calling party, for example, a calling party who hears a “work” voicemail system greeting when he/she dialed the called party's “home” number. In other embodiments, the SVMSs 24, 26 can be configured to play a greeting and then forward the call to an MVMS 28 for message storage. The SVMSs 24, 26 can be configured to forward the call with a message informing the calling party that the call is being forwarded to an MVMS 28.

The law does not require and it is economically prohibitive to illustrate and teach every possible embodiment of the present claims. Hence, the above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the disclosure. Variations, modifications, and combinations may be made to the above-described embodiments without departing from the scope of the claims.
